(write errors poison the chan so the next T* gets an Rerror.) great for annoying people by streaming video in the unix room. brucee ----- Original Message ----- From: To: <9fans@cse.psu.edu> Sent: Thursday, July 31, 2003 6:29 PM Subject: [9fans] 9p & read-ahead > Hi, > > I am thinking of adding read-ahead to a 9p server. > Is this a sensible thing to do?
